Open Radar Community today reported a bug in Apple's Mac systems. According to a post, a eight characters text will crash almost any application on your Mac. When you type "File:///" (The capital 'F' is important) in some Mac application like TextEdit, it will crash the screen. It is figured out that, the bug is inside Data Detectors, a feature that lets apps recognize dates, locations, and contact data, making it easy for you to save this information in your address book and calendar. Since the bug has been reported to Apple, it will likely be patched at some point. A reader copy posted the crash dump at Pastebin.
